Windows Server 08 Installation Error/Glitch?

[grimdoomer]

Well I just got done installing Windows Server 08. It booted for the first time and said I needed to set a password before I could continue. Ok, so I typed a password in, and it said "Password does not match expected length or complexity. Then it asked me to type it in again. So after trying for like 10 minutes, using passwords with lengths ranging from 3-14 letters and numbers, I gave up. So I'm wondering if there is some way I can skip it, or is there a certain password I have to type in?
